IPC: G02B19/00
Filed: 1996-10-16
Abstract: PROBLEM TO BE SOLVED: To prevent the braking of a partial element caused by the heat of a condensed light point by separating the condensed light point of a second optical integrator from each partial lend element. SOLUTION: Each lens element groups constituting the second optical integrator 5 is constituted of a pair of square pole-like partial lens elements 5a and 5b arranged along an optical axis on order from the side of a light source with a specified interval. Then the focal position of the front side (light source side) of each lens element group is neatly aligned with the incident plane of the first lens element 5a, and also the rear side focal position F of each lens element group is separated from the light exist surface of the second partial lens element 5b on the side of an object to be irradiated by a specified distance.  Thus, a parallel luminous flux made incident on the incident plane of the first partial lens element 5a at each lens element group forms the condensed light point of a luminous flux at a position F separated from the light exit surface of the second partial lens element 5b on the side of the object to be irradiated only by the specified distance.

Abstract: PURPOSE:To constitute an alarm detecting circuit of a small circuit size even if the number of continuously detected '1's is increased by setting up the output voltage of the circuit to a level higher than its threshold and sending an alarm from a comparator when the fixed number of continuous '1's is applied to an integrating circuit, and immediately after applying '0', turning the output voltage immediately to the '0' state by a three-state buffer. CONSTITUTION:Since a power supply voltage Vcc is applied to the terminal 3 of the three-state buffer 5, a terminal 2 is turned to high impedance by applying data '1' to a terminal 1 or turned to '0' by applying data '0'. Namely, when '1' is inputted, the three-state buffer 5 is almost disconnected from the integrating circuit 4, a capacitor 41 is electrostatically charged with the inputted '1', and when the charging voltage exceeds the threshold Vth, an AIS alarm is sent from the comparator 6. Immediately after inputting '0', the charge accumulated in the capacitor 41 is discharged through the terminals 2, 1 and the capacitor is immediately turned to the '0' state, but when '1' is inputted, the capacitor 41 is charged again.

Title: Transfer paper carrying method
Inventor: NAKAO FUMIO
IPC: G03G21/14
Filed: 1996-10-17
Abstract: PROBLEM TO BE SOLVED: To increase the transfer paper carrying speed without increasing the cost by making the transfer paper carrying speed at a fixing part lower than the transfer paper carrying speed at a transfer part in an image forming device. SOLUTION: A transfer paper (a) fed from a resist roller 14 at carrying speed V1 is carried to the transfer part 15 under a photoreceptor 3 which keeping a distance L1, then, a toner image is transferred to the transfer paper (a). Thereafter, the paper reaches the fixing part 17 through a carrying belt 16, then, the paper is pressurized and heated at the carrying speed V2 so as to fix the toner image. In this case, the carrying speed V2 is made lower than the carrying speed V1. That is, the distance L2 between sheets of the transfer paper (a) after passing through the fixing part 17 is controlled to be zero as near as possible, and the distance L2 is allowed to be smaller than the distance L1.  Thus, the carrying speed V2 can be made lower than the carrying speed V1, then, a fixation nip time is secured only by reducing the carrying speed V2 even in the case of increasing the carrying speed V1, so that the fixation is maintained in a good state.

Title: Optical disk information recording and reproducing device
Inventor: MURATA SEIJI
IPC: G11B7/0055
Filed: 1987-11-20
Abstract: PURPOSE:To use photochromic materials as an optical recording medium to record and reproduce information by using ultraviolet rays as the beam of one pickup and using visible rays as the beam of the other. CONSTITUTION:Photochromic materials are used as the optical recording medium, and an erasing pickup 5 and a recording/reproducing pickup 6 are provided independently of each other, and ultraviolet rays are used as the beam of one pickup 5, and visible rays are used as the beam of the other pickup 6. Photochromic materials are colored to raise the reflection factor because ultraviolet rays are used for the erasing pickup 5, and photochromic materials are achromatized and are switched to the transparent state to reduce the reflection factor because visible rays are used for the recording/reproducing pickup 6. Thus, recording is possible, and the beam intensity of visible rays is reduced and a recording track is scanned to reproduce recorded information based on the difference of reflection factor.

Abstract: PROBLEM TO BE SOLVED: To form a ball which is not deformed and not eccentric from the center of a wire by applying a magnetic field to a discharge spark to bend the spark so that the spark corresponding to the wire may be below the wire. SOLUTION: A discharge electrode 3 is mounted on a discharge rod 7 on which a permanent or electromagnetic magnet 10 is mounted to apply a magnetic field to a discharge spark 8 between the top end of a wire 2 and discharge electrode 3. With the wire 2 set to + pole and discharge electrode to - pole, the magnet 10 provides the S at the discharge electrode 3 and N poles at the opposite side. The magnetic field 11 by the magnet 10 acts on that 21 due to a current 20 to bend the spark 8 downwards so that discharge spark corresponding to the wire 2 may be below the wire 2. This, even in a fixed discharge electrode system, forms a ball which is not deformed and not eccentric from the center of the wire 2.
